FIELD OF INVENTION

The present invention relates to a cold storage heat exchanger, and moreparticularly, to a cold storage heat exchanger capable of increasingcooling comfort for a user and minimizing energy and time consumed uponperforming a re-cooling by discharging cooled air stored in a coldstorage tube upon operating an air conditioner of a vehicle even in thecase in which an engine is stopped because the cold storage tube isprovided between refrigerant tubes in an evaporator used in an airconditioner apparatus of the vehicle to thereby prevent a rapid increasein an interior temperature of the vehicle.

BACKGROUND OF THE INVENTION

An air conditioner system, which is an apparatus absorbing interior heatof a vehicle and discharging it to the exterior of the vehicle betweentwo environments having a temperature difference, generally includes anevaporator absorbing heat from a surrounding, a compressor compressing arefrigerant, a condenser discharging the heat to the surrounding, and anexpansion valve expanding the refrigerant.

In addition, in an air conditioner, an actual cooling operation occursby the evaporator in which the refrigerant in a liquid state isevaporated by absorbing an amount of heat as much as evaporation heatfrom the surrounding. The refrigerant in a gas state introduced from theevaporator to the compressor is compressed to high temperature and highpressure by the compressor, heat of liquefaction is discharged to thesurrounding during a process in which the compressed refrigerant in thegas state passes through the condenser and is liquefied, and theliquefied refrigerant becomes wet saturated steam of low temperature andlow pressure by being again passed through the expansion valve and isthen again introduced into the evaporator and evaporated, such that acycle is performed.

However, since the air conditioner apparatus of the vehicle is based ondriving force of an engine, a cooling operation is not performed in thecase in which the vehicle is idling or is parked for a short time. Inaddition, in the case in which a temperature of an exterior environmentof the vehicle is very high, if the air conditioner apparatus is notoperated even for a short time as described above, the interiortemperature of the vehicle is very rapidly increased and when thevehicle is again driven, the operation of the air conditioner apparatusis resumed. As a result, a cooled wind does not rapidly rise, therebysignificantly decreasing comfort for a user.

In a recent vehicle industry, as an interest in an environment andenergy is globally increased, a research into fuel efficiencyimprovement has been conducted and a research and development intolightness, miniaturization, and high functionalization has beencontinuously conducted to satisfy various consumer desires.

Particularly, a research and development into a hybrid vehiclesimultaneously using power of the engine and electricity energy has beenincreased due to the fuel efficiency improvement and emission regulationof exhaust, or the like, and the hybrid vehicle mainly adopts an idlestop and go system allowing the engine to be automatically stopped whenthe vehicle is stopped such as waiting for a signal and to be restartedby again manipulating a transmission.

However, since the air conditioner apparatus of the hybrid vehicle isalso operated by the engine, in the case in which the engine is stopped,the compressor is also stopped, such that the temperature of theevaporator is rapidly increased, thereby decreasing comfort for theuser.

In addition, since the refrigerant in the evaporator is easilyevaporated even at room temperature, even in the case in which therefrigerant is evaporated for a short time in which the compressor isnot operated and the engine is again operated to thereby operate thecompressor and the evaporator, the evaporated refrigerant needs to becompressed and liquefied. Therefore, it takes a long time to supply thecooled wind to the interior and a total amount of energy consumption maybe increased.

In order to solve the problem as described above, a variety of forms ofheat exchangers using a cold storage material storing cooled air havebeen suggested.

FIGS. 1 and 2 are views showing a heat exchanger having a cold storagematerial stored therein according to the related art.

The heat exchanger having the cold storage material stored thereinaccording to the relate art as shown in FIG. 1 includes a pair of tanksformed to be spaced apart from each other by a predetermined distanceand in parallel with each other, where the tank includes a first tank 21and a second tank 31. In addition, the first tank 21 is coupled to afirst header 20 and the second tank 31 is coupled to a second header 30,such that independent channels are respectively formed.

In addition, several refrigerant tubes 40 and cold storage tubes 50having both ends fixed and forming a heat exchanging medium channel arecoupled to the first header 20 and the second header 30, respectively.

In this case, as shown in FIG. 2, since the refrigerant tube 40 isconfigured in the cold storage tube 50, channels of the heat exchangingmedium and the cold storage material are respectively formedindependently from each other.

Therefore, since it is difficult to form independent spaces of the coldstorage material and the heat exchanging medium, a structure thereof iscomplex and production efficiency is decreased.

In addition, a cold storage heat exchanger of a stacked plate typeaccording to the related art disclosed in Korean Patent Laid-OpenPublication No. 10-2009-0108380 has tubes configured by three columns inwhich the refrigerant is introduced into two tubes of both sides and thecold storage material is introduced into a middle tube. However, sinceit is difficult to secure an internal space in which the cold storagematerial is present and an amount of introduced cold storage material issmall, it is difficult to obtain adequate cold storage performance.

In addition, in the heat exchanger having the cold storage materialstored therein according to the related art, since there is highprobability of the cold storage material interrupting a flow of the heatexchanging medium or the cold storage material and the heat exchangingmedium being mixed with each other, other problems may be caused.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, a cold storage heat exchanger according to the presentinvention having a configuration as described above will be described indetail with reference to the accompanying drawings.

FIGS. 3 and 4 are an exploded perspective view and an assemblyperspective view showing the cold storage heat exchanger according tothe present invention.

As shown, the cold storage heat exchanger according to the presentinvention is configured to include a pair of header tanks 100 which arepartitioned by partition walls and formed in three columns so thatrefrigerant header tanks 110 having a refrigerant flowing therein areformed in a first column and a third column and a cold storage headertank 120 having a cold storage material stored therein is formed in asecond column between the first column and the third column, and arespaced apart from each other by a predetermined distance and formed tobe in parallel with each other; an inlet manifold 160 and an outletmanifold 170 formed at both ends of the header tank 100 and being incommunication with the refrigerant header tanks 110 of the first columnand the third column, the inlet manifold 160 being introduced with arefrigerant and the outlet manifold 170 discharging the refrigerant; aplurality of refrigerant tubes 200 having both ends connected to therefrigerant header tanks 110 of the first column and the third columnformed to be spaced apart from each other by the predetermined distanceand having the refrigerant flowing therein; and a plurality of coldstorage tubes 300 having both ends connected to the cold storage headertank 120 of the second column formed to be spaced apart from a pair ofcold storage header tanks 120 by the predetermined distance and havingthe cold storage material stored therein.

First, the pair of header tanks 100 are formed to be spaced apart fromeach other by the predetermined distance and to be in parallel with eachother in a vertical direction. In this case, the respective header tanks100 have the refrigerant header tanks 110 formed in the two columnsalong a length direction thereof and the cold storage header tank 120formed between the refrigerant header tanks 110 of the two columns. Thatis, the header tank 100 are formed in the three columns and have thecold storage header tank 120 formed in the middle column so as to enablethe cold storage material to be stored or flown.

As such, the header tanks 100 are formed in the three columns to bedisposed at upper and lower portions, respectively, and have therefrigerant tubes 200 and the cold storage tube 300 coupled thereto. Inthis case, the refrigerant tubes 200 and the cold storage tube 300 areconnected to each other so that both ends thereof are connected betweenthe pair of header tanks 100 disposed on an upper portion and a lowerportion, where the refrigerant tubes 200 are configured so that bothends thereof are connected to the refrigerant header tanks 110 of thetwo columns of the header tanks 100 to enable a heat exchanging mediumto be flown and the cold storage tube 300 is configured so that bothends thereof are connected to the cold storage header tank 120 to enablethe cold storage material to be flown and stored.

That is, as shown in FIG. 6, the refrigerant tubes 200 are formed in thetwo columns at both sides and the cold storage tube 300 is formed in onecolumn at the middle, thereby configuring the tubes of the threecolumns.

In addition, fins 400 are coupled to the refrigerant tubes 200 and thecold storage tube 300 to be in contact with each other and are formed ina plate having a zig-zag form and a corrugated form, thereby serving toimprove heat exchanging efficiency with the heat exchanging medium orthe cold storage material passing through interiors of the tubes 200 and300.

In summary, the cold storage heat exchanger 1000 according to thepresent invention has a structure in which a cold storage unit of onelayer is configured between heat exchangers of two layers.

Here, baffles 130 partitioning an internal space of the refrigerantheader tank 110 may be formed in the refrigerant header tank 110 of theheader tank 100 so as to control a flow of the heat exchanging medium.In this case, the baffles 130 may be formed in the refrigerant headertank 110 and a plurality of baffles 130 may be formed at variouspositions, thereby making it possible to control the flow of therefrigerant.

In addition, the header tank 100 may have the inlet manifold 160introduced with the heat exchanging medium and the outlet manifold 170discharging the heat exchanging medium, which are coupled thereto, andthe inlet manifold 160 and the outlet manifold 170 are connected to bothends of the refrigerant header tanks 110 of the two columns of theheader tanks 100, thereby making it possible to form two channels inwhich the heat exchanging medium may flow.

In addition, a cold storage material injecting part 151 is formed in oneside of the cold storage header tank 120, which may be configured toinject the cold storage material into the cold storage header tanks 120and the cold storage tube 300. In this case, the cold storage injectingpart 151 may be in communication with the cold storage header tank 120by forming an opening in an end cap 150 coupled to the ends of theheader tanks 110 and 120 and may prevent a leakage of the cold storagematerial by blocking the cold storage material injecting part 151 by aplug, a blocking bolt, or the like after the cold storage material isinjected.

As such, since the cold storage heat exchanger according to the presentinvention has two channels of the heat exchanging medium formed thereinand the cold storage header tank 120 and the cold storage tube 300,which are separate cold storage material storing parts, formedtherebetween, the cold storage material and the heat exchanging mediummay secure independent spaces, there is a low probability of the coldstorage material interrupting the flow of the heat exchanging medium orthe cold storage material and the heat exchanging medium being mixedwith each other, and production efficiency may be improved due to asimplified structure.

In addition, since there is no a refrigerant communication passagestructure connecting the refrigerant tubes of the two columns, therefrigerant channel may be easily configured and since the refrigerantchannel is configured by the two columns to decrease an amount of flowof the heat exchanging medium passing through the refrigerant headertank and the refrigerant tube of each column, a pressure drop of theheat exchanging medium may be decreased

In addition, the cold storage heat exchanger according to the presentinvention has the two refrigerant channels formed therein as shown inFIG. 5, where flow directions of the refrigerant flowing along the tworefrigerant channels may be formed to be different from each other byforming shapes of the inlet manifold 160 and the outlet manifold 170 toallow the two channels to be formed in one manifold.

In addition, the refrigerant tubes 200 and the cold storage tube 300 areformed in an integral tube 500, such that the cold storage tube 300 maybe formed between the refrigerant tubes 200 of the two columns and theintegral tube 500 may have cut grooves 510 formed in both ends thereofto be inserted into communication holes 140 formed in the header tank100.

As shown in FIG. 7, the integral tube 500 is formed so that the coldstorage tube 300 is disposed between the refrigerant tubes 200 of thetwo columns and has the cut grooves 510 respectively formed in both endsthereof, such that the refrigerant tubes 200 and the cold storage tube300 are formed to be respectively inserted into the communication hole140 of the refrigerant header tank 110 and the communication hole 140 ofthe cold storage header tank 120, thereby making it possible to couplethe integral tube 500 between the pair of header tanks 100 disposedvertically in one column.

Therefore, as compared to the case in which the refrigerant tubes 200 ofthe two columns and the cold storage tube 300 of one column arerespectively coupled to the header tank 100, when the refrigerant tubes200 and the cold storage tube 300 are manufactured in the integral tube500, the integral tube 500 may be very easily coupled to the header tank100.

In this case, the integral tube 500 may be manufactured by performing anextrusion molding for the refrigerant tubes 200 and the cold storagetube 300 in an integral type and the integral tube 500 inserts both endsthereof into the pair of header tanks 100 and is then coupled thereto bya brazing, thereby preventing an occurrence of a leakage of the heatexchanging medium and the cold storage material.

In addition, the refrigerant header tanks 110 and the cold storageheader tank 120 may be formed to be spaced apart from each other by apredetermined distance as shown in FIG. 8.

In addition, as the cold storage heat exchanger 1000 formed as describedabove is configured to further include a pump 600 and a reservoir 700which are connected to the cold storage header tank 120, it may beconfigured so that the cold storage material is circulated along thecold storage header tank 120 and the cold storage tube 300.

As shown in FIG. 9, the above-mentioned configuration is a configurationin which the pump 600 capable of circulating the cold storage materialand the reservoir 700 in which the cold storage material is stored areseparately provided outside the cold storage heat exchanger 1000, suchthat the pump 600 is connected to one side of one cold storage headertank 120 by a pipe 900 and the reservoir 700 is connected to one side ofanother cold storage header tank 120 by the pipe 900. Thus, since thecold storage heat exchanger 1000 is configured so that the cold storagematerial is circulated through the reservoir 700, the pump 600, the coldstorage header tank 120, the cold storage tube 300, and the reservoir700, the amount of cold storage material is increased, thereby making itpossible to cool interior air of a vehicle for a long time even in thecase in which an engine of the vehicle is stopped.

In this case, the pump 600 may be connected to a controller 800, therebycontrolling the circulation of the cold storage material by thecontroller 800. That is, the controller 800 may control the pump 600 tobe operated when the interior temperature of the vehicle is maintainedat a proper temperature to circulate the cold storage material and storecooled air in a large amount of cold storage material stored in thereservoir 700 and may control the pump 600 not to be operated when theinterior temperature of the vehicle needs to be decreased to prevent thecirculation of the cold storage material so that the cold storagematerial does not absorb the cooled air of the refrigerant tube 200 andthe interior temperature of the vehicle may be decreased in a shorttime.

In addition, a cold storage heat exchanger 1000 according to the presentinvention is configured to include a pair of header tanks 100 havingrefrigerant header tanks 110 formed in two columns to allow arefrigerant to flow and formed to be spaced apart from each other by apredetermined distance and be in parallel with each other; an inletmanifold 160 and an outlet manifold 170 formed at both ends of theheader tank 100 and being in communication with the refrigerant headertanks 110 of the two columns, the inlet manifold 160 being introducedwith a refrigerant and the outlet manifold 170 discharging therefrigerant; a plurality of refrigerant tubes 200 having both endsconnected to the refrigerant header tanks 110 of the two columns formedto be spaced apart from each other by the predetermined distance andhaving the refrigerant flowing therein; and a cold storage tube 300provided between the refrigerant header tanks 110 of the two columns tohave a cold storage material stored therein.

The above-mentioned configuration is the similar configuration as theembodiment as described above, but as shown in FIGS. 10 and 11, theheader tank 100 does not have the cold storage header tank 120 formedtherein and is configured by only the refrigerant header tanks 110 ofthe two columns, such that the refrigerant tubes 200 of the two columnsare coupled to the refrigerant header tanks 110 of the two columns. Inaddition, the cold storage tank 300 is provided between the refrigeranttubes 200 of the two columns, such that the cold storage material isstored in the cold storage tube 300. In this case, the cold storage tube300 is configured to have both sides coupled to be in contact with therefrigerant tubes 200 of the two columns, thereby making it possible toabsorb cooled air. That is, the refrigerant tube 200 has both endsconnected to the refrigerant header tank 110 so as to allow the heatexchanging medium to flow therein, while the cold storage tube 300 isformed in a pack form in which both ends thereof are blocked, therebystoring the cold storage material therein

Thus, since the cold storage tube 300 in which the cold storage materialis stored is formed in the pack form, there is no need to form the coldstorage header tank 120 in the header tank 100 and connect the coldstorage tube 300 to the header tank 100, such that the configuration maybe simple and the cold storage tube 300 may be easily assembled andreplaced.

In this case, the refrigerant header tanks 110 of the two columns may beformed to be spaced apart from each other by the predetermined distance.This means that the respective refrigerant header tanks 110 of the twocolumns are configured to be separately formed and spaced apart fromeach other by the predetermined distance in a width direction, where therefrigerant header tanks 110 of the two columns may be fixed and incommunication with each other by having an integral end cap 150 or themanifolds 160 and 170 coupled to ends of the refrigerant header tanks110.

Thus, since the refrigerant header tanks 110 of the two columns areconfigured to be spaced apart from each other by the predetermineddistance, the heat exchanger of two layers is manufactured, such thatthe cold storage tube 300 of the pack form is assembled to be coupledbetween the refrigerant tubes 200 and the integral end cap 150 or themanifolds 160 and 170 are coupled to both ends of the refrigerant headertank 110, thereby making it possible to manufacture one cold storageheat exchanger. In addition, since the refrigerant header tanks 110 ofthe two columns are configured to be spaced apart from each other by thepredetermined distance, condensate water generated on surfaces of therefrigerant tube 200 and the cold storage tube 300 upon beingheat-exchanged may be discharged between the refrigerant header tanks110 of the two columns configured on a lower portion, thereby easilydischarging the condensate water.

In addition, the refrigerant header tanks 110 of the two columns formedon an upper portion among the pair of header tanks 100 are formed to belarger than the refrigerant header tanks 110 of the two columns formedon a lower portion, such that the refrigerant header tanks 110 of thetwo columns formed on the lower portion may be formed to be spaced apartfrom each other by the predetermined distance in the width direction.

Thus, since the generated condensate water is discharged toward therefrigerant header tanks 110 configured on the lower portion as shown inFIG. 12, the refrigerant header tanks 110 of the two columns configuredon the upper portion are formed in an integral type and are formed to belarge, thereby making it possible to increase an amount of heatexchanging medium stored and flowing therein. As a result, flowresistivity of the heat exchanging medium flowing in the refrigerantheader tanks 110 may be decreased. In addition, since the refrigerantheader tanks 110 configured on the lower portion are formed to be spacedapart from each other by the predetermined distance, the cold storagetube 300 formed in the pack form between the refrigerant header tanks110 may be replaced and assembled.

In addition, the cold storage heat exchanger is configured to furtherinclude a cold storage material storing vessel 310 coupled to lowersides of the refrigerant header tanks 110 of the two columns formed onthe lower portion and connected to a lower end of the cold storage tube300, where the cold storage material storing vessel 310 may be providedwith a condensate water discharging hole 311 vertically penetratingthrough thereof. That is, as shown in FIG. 13, the cold storage materialstoring vessel 310 is formed in a length direction so that both sidesare coupled to the lower sides of the refrigerant header tanks 110 ofthe two columns configured on the lower portion and the lower end of thecold storage tube 300 is connected to the cold storage material storingvessel 310, and a plurality of discharging holes 311 are formed in thecold storage material storing vessel 310 to vertically penetrate throughthereof in order to discharge the generated condensate water. Thus,since a large amount of cold storage material may be stored in the coldstorage material storing vessel 310, a large amount of cooled air may bestored. In addition, since the cold storage material may be cooled bythe condensate water flowing around the cold storage material storingtank 310, efficiency in cold storage may be further improved.

In addition, the manifolds 160 and 170 or the end cap 150 may beprovided with a cold storage tube supporter 320 coupled to the coldstorage tube 300.

In this case, as shown in FIG. 14, the cold storage tube supporter 320may be formed to be long so that both ends thereof are coupled to theinlet manifold 160 and the outlet manifold 170 formed at both ends ofthe header tank 100 of the upper side, or the cold storage tubesupporter 320 may be formed to be long so that both ends thereof arecoupled to a pair of integral end caps 150 formed at both ends of theheader tank 100 of the lower side, and the cold storage tube supporter320 may be coupled to the cold storage tubes 300 to serve to support thecold storage tubes 300.

The present invention is not limited to the above-mentioned embodimentsbut may be variously applied, and may be variously modified by thoseskilled in the art to which the present invention pertains withoutdeparting from the gist of the present invention claimed in the claims.
